About methods of assessment

Mathematics performance

PISA (Programme for International Student Assessment) examined the students’ proficiency in maths through the test that covered range of mathematical skills and knowledge. Its results were then assessed based on a scale divided to 6 levels, with higher levels indicating higher general proficiency and understanding. First level started from 358 points and last level was 669 points and above.

Career expectations

Based on students’ reports PISA examined percentage of students who don’t have any clear idea on their future job when they are around 30 years old. Whereas, students who do have some plan on that were asked to assign whether their expected occupation is high, medium or low skilled in terms of level it takes in ISCO (International Standard Classification of Occupations).

Test results among countries:

Connection between maths test results and future job aspirations

Correlation plots

Plot 1

Plot above indicates a very slight tendency that students from countries with lower averages of the scores are less likely to plan about their future job. Most significant deviations appeared for marginal data, which means that highest percentage of students who don’t have idea on their future occurred in countries with lowest mean of the scores and the other way round.

Plot 2

On the other hand results showed by this plot are not that obvious. Highest percentage of students planning to have a high-skilled occupation occurred in countries with either higher or lower mean of the scores in test and there isn’t any visible trend through the plot.
